Using the memory trick SOH-CAH-TOA can help Year 12 students learn trigonometric ratios more easily. Here’s a simple breakdown:
SOH: This means Sine = Opposite / Hypotenuse. It helps you remember that the sine of an angle is about the length of the side opposite the angle and the hypotenuse (the longest side) in a right triangle.
CAH: This stands for Cosine = Adjacent / Hypotenuse. This is a helpful way to remember how the length of the side next to the angle (the adjacent side) relates to the hypotenuse.
TOA: This represents Tangent = Opposite / Adjacent. It shows how the opposite side relates to the adjacent side.
By using these easy phrases, students can remember the ratios during tests or while solving math problems.
I remember when I first learned this, it was really tough. But once I started using SOH-CAH-TOA, things became much clearer! It made working with trigonometry a lot less scary.
